RE: [Elecraft] Antennas for use with Elecraft T1 ATU

Kieth, A dipole cut for 40 meters will provide a high feedpoint impedance on 20 - and the L network used in the Elecraft tuners do not do high impedances very well. Of course, all that does depend on your feedline length as well as the flattop length - the feedline will act as an impedance

[Elecraft] Input vs. output power question

I intend to join the IARU HF contest in the QRP category (i.e. 5 watts output). I have got a RG58 going to my inverted V antenna. The coax is about 45 meters in length (roughly 135 feet). How much power should I request from my K2 to get 5 watts output from the antenna? 73! de TA2RX

Craig, Thanks for the info. I checked out the Elecraft baluns you mention and will order one up. This sounds like a reasonable size setup for the times when I can get up a center pole to support the antenna. Is there a preferred height for the apex or do I just go as high as I can? I do

OK I managed to whittle a plastic tuning wand to the correct shape in order to adjust the 2 tuning capacitors for 20M and the 1 for 40M. The situation I mentioned about touching the board and having the signal come way, way up is only happening when I transmit my K1-4 into the DL1 in the shack.

RE: [Elecraft] KX1 Receiver alignment - further information

Vin, Congratulations on completing your KX1 your fun is just beginning. Your audio will naturally be higher on 40M, at least mine is. Low audio output is a common subject on this net for the KX1. I suspect your unit is fine. Sensitive earphones are a necessity with the KX1, check your

[Elecraft] LO Power for XV transverters

I have a full stack of XVs and just migrated to a K2 for IF. Each of the XVs has a crystal oven. I notice in the stock config for K2, the LO power jumper at JP9 is 1-2. (All other jumpers are set as recommended for K2 IF with 0dBm drive and split paths.) Following the schematic it seems

Re: [Elecraft] Input vs. output power question

Bekir: The technical answer to your question is as follows. The loss of your coax depends on the SWR and frequency. 45 meters of CQ125 (a high quality version of RG-58) at 14 MHz with an SWR of 2:1 has an idealized loss of 2.7 dB. If you request 9.5 Watts on your K2, you would get close to 5

RE: [Elecraft] LO Power for XV transverters

Raj, The full set of oscillator and oven power jumper options is on page 74 of the transverter manual. If you are using the oven and want the best stability, I would believe you would want the oscillator and oven on all the time (even when the K2 is off), and for that, the jumper is placed on 4

RE: [Elecraft] Low SSB TX power on K2

Cal, First check the voltage on the collectors of Q2 and Q3 during transmit - you should find close to 8 volts. It sounds to me like you are not getting an adequate audio signal into the balanced modulator (U4 on the KSB2 board). Without some tool to observe the audio signal, that may be a

Re: [Elecraft] Antennas for use with Elecraft T1 ATU

I find the T1 does very well with a very high impedance. I end feed 1/2 wave wire connected right to the T1 with a counterpoise and it matches right up! I ran a test and the T1 can match a 4700 ohm resistor. So it's not bad with high resistance. 73 Karl

RE: [Elecraft] Antennas for use with Elecraft T1 ATU

Rick, Like everything else It all depends... In your particular case, it depends on how the elements are oriented - and that includes the counterpoise. It also depends on the proximity of ground and other objects. Is the counterpoise in the air, or is it laying on the ground? That is the

Hi folks, I have resolved the signals getting loud when I touch the board mystery with help, but there is still something amiss. Upon further testing, the receiver appears to be profoundly deaf. It does hear some signals on 40, and even some on 20, but not nearly as well as it should. However, I

RE: [Elecraft] KX1 Recvr nearly deaf (Was KX1 receiver alignment)

Some additional data. Voltages at U4, U5 and U6 check out OK. However, the base voltages at Q7 and Q9 are out of spec. Base at Q7 should be about .7V, but is about .37V and base at Q9 should be about .3V but is about .15V. I am continuing my troubleshooting, but welcome any and all advice.

RE: [Elecraft] KX1 Recvr nearly deaf (Was KX1 receiver alignment)

Do you have the KXAT1 antenna tuner installed? If not, is the required jumper in place across pins 1 and 3 of J7 (page 41, right column, last step of the manual). That's the three-pin connector *closest* to the antenna jack. If so is it making contact with the pins? Without that jumper, the

RE: [Elecraft] KX1 Recvr nearly deaf (Was KX1 receiver alignment)

Vin, The voltage at the base of Q7 should be at or very near zero during receive. The 0.7 volts is what is expected during transmit. Try grounding the base of Q7 and see if the receiver comes more alive. If it does, you must chase down the source of the voltage on the base - first check pin 7
